Consider the following weekly salaries 275 616 773 711 724 6

Consider the following weekly salaries:

$275, $616, $773, $711, $724, $610, $380, $726, $132, $188

Round all answers to the nearest penny.

(1) What is the mean weekly salary? $---------------.

Determine the five number summary of weekly salaries:

What conclusion can you draw about the distribution of these salaries?

(1) The distribution is skewed right because the median is greater than the mean.

(2) The distribution is skewed right because the mean is greater than the median.

(3) The distribution is skewed left because the median is greater than the mean.

(4) The distribution is skewed left because the mean is greater than the median.

(5) The distribution is normally distributed because the mean is approximately equal to the median, within $20.

Enter number of your choice here----------------.

Solution

Mean of weekly series is (275+616+....+132+188)/10= 513.5

Min = 132

Q1= 275

Med= 613

Q3= 724

Max= 773

In this case mean (513.5) is less than median (613), threfore distribution of weekly series is lesft skewed.

in this case distribution is not normally distributed because mean is too far from median as difference of median and mean is 99.5.
